Description

Technical Field

[0001] This invention relates to the field of surface treatment equipment technology, specifically to an integrated water-circulating copper wire wheel rust removal and polishing equipment. Background Technology

[0002] In industries such as machining, hardware manufacturing, and parts production, the surfaces of various metal workpieces often require water polishing treatments such as grinding, rust removal, and polishing. Copper wire wheel water polishing equipment is the core equipment for such operations. Current copper wire wheel water polishing equipment has several shortcomings: First, the water supply structure is poorly designed, often using external water pipe connections, leading to uneven water flow distribution and a lack of dedicated side water pipe interfaces. External water pipe connections are cumbersome and have poor adaptability. Second, the drainage structure is inadequate, with drainage pipes not reaching the bottom of the equipment, causing wastewater to accumulate inside, affecting polishing operations and corroding internal components. Third, the control structure is disorganized, with power indicators, motor switches, and water pump switches not arranged in a standardized manner, leading to accidental operation. Furthermore, the equipment's dimensions are poorly planned, occupying a large space and lacking flexibility to adapt to different workshop scenarios. Fourth, the functional modules of existing water polishing equipment have low integration; the water supply, polishing, and drainage systems are independent, resulting in poor collaborative operation, low efficiency in workpiece water polishing, and insufficient overall stability and durability.

[0003] Existing copper wire wheel water polishing equipment has the following shortcomings: water supply is mostly external direct discharge type, cooling water cannot be circulated and reused, water resources are wasted and metal debris is easy to block the pipeline; the tension of the transmission belt requires disassembly of the motor for adjustment, which is cumbersome to maintain, has long downtime and is prone to slippage; the motor and water pump are linked for control, and it is impossible to adjust the water supply or speed under no-load, lacking stepless speed regulation means and poor process adaptability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an integrated water-circulating copper wire wheel rust removal and polishing device, which solves the problems of existing equipment such as the inability to recycle and reuse cooling water, significant water waste, cumbersome maintenance of transmission belt tensioning, the inability to independently control the motor and water pump, and the lack of stepless speed regulation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: comprising a frame, a polishing spindle assembly, a drive transmission assembly, a water circulation spray assembly, and an electrical control assembly. The polishing spindle assembly is horizontally mounted in the middle of the frame. The drive transmission assembly is mounted in the lower part of the frame and is connected to the polishing spindle assembly via a transmission belt. The water circulation spray assembly is fixed in the lower middle part of the frame and sprays water towards the polishing area of ​​the polishing spindle assembly. The electrical control assembly is mounted in the upper front part of the frame and is electrically connected to the drive transmission assembly and the water circulation spray assembly, respectively.

[0006] Preferably, the polishing spindle assembly includes a rotating shaft and a retainer, and a copper wire wheel rotating shaft. The rotating shaft and retainer are laterally locked and installed on the crossbeam of the frame. The copper wire wheel rotating shaft extends horizontally out of the operating side of the frame. A copper wire wheel is assembled at the outer end of the copper wire wheel rotating shaft, and a driven pulley is installed at the inner end of the copper wire wheel rotating shaft.

[0007] Preferably, the water circulation spray assembly includes a circulating water nozzle, a circulating water tank, and a circulating water pump. The circulating water tank is horizontally fixed to the lower crossbeam of the frame. The circulating water pump is placed inside the circulating water tank. The outlet of the circulating water pump is connected to a pipe that extends upward to the top of the frame. The end of the pipe is bent to form the circulating water nozzle, which sprays water in a directional manner toward the contact area between the copper wire wheel and the workpiece.

[0008] Preferably, the electrical control components include a power indicator, a motor switch, a water pump switch, and a speed controller. The speed controller is electrically connected to the motor. The motor switch is connected in series in the power supply circuit of the motor. The water pump switch is connected in series in the power supply circuit of the circulating water pump. The power supplies for the motor and the circulating water pump are independent of each other. The power indicator is connected in parallel to the power supply input terminal of the whole machine.

[0009] Preferably, the drive transmission assembly further includes a motor, a motor mounting bracket, and a spiral clamping bolt. The motor is mounted on the motor mounting bracket, and the motor output shaft is equipped with a drive pulley. The drive pulley is connected to the driven pulley at the inner end of the copper wire wheel shaft via a transmission belt. The bottom of the motor mounting bracket is hinged to the bottom of the frame.

[0010] Preferably, a spiral clamping bolt is installed on the rear side of the motor mounting bracket. The screw end of the spiral clamping bolt abuts against the rear side of the motor mounting bracket. Rotating the spiral clamping bolt pushes the motor mounting bracket to flip outward around the hinge point to tension the transmission belt. Rotating the spiral clamping bolt in the opposite direction relaxes the transmission belt.

[0011] Preferably, the circulating water tank is equipped with a filter screen, which is horizontally mounted at the top of the circulating water tank. Wastewater carrying metal fragments flows back to the circulating water tank by gravity and is filtered by the filter screen. The filtered water is then pumped back to the circulating water nozzle for reuse.

[0012] Preferably, the electrical control components are arranged sequentially from top to bottom on the front of the frame, including a speed controller, a power indicator, a motor switch, and a water pump switch.

[0013] Preferably, the frame is a stainless steel welded enclosed vertical frame, and the polishing spindle assembly, drive transmission assembly, water circulation spray assembly and electrical control assembly are all integrated and installed in the vertical frame. The power supply line is built into the frame and is insulated and waterproofed.

[0014] Beneficial effects Compared with the prior art, the present invention provides an integrated water-circulating copper wire wheel rust removal and polishing device, which has the following beneficial effects: 1. This integrated water-circulating copper wire wheel rust removal and polishing equipment utilizes a water-circulating spray assembly. Water stored in the circulating water tank is pressurized and transported by a circulating water pump through pipelines to the circulating water nozzles at the top of the frame. The nozzles spray water directionally towards the contact and friction area between the copper wire wheel and the workpiece. The cooling water carries away the frictional heat and, carrying metal debris, flows back into the circulating water tank below by gravity. After solid debris is intercepted by the filter screen inside the tank, the clean water is again pumped to the nozzles. This achieves the effects of circulating and reusing polishing cooling water, significantly saving water resources, zero direct discharge of wastewater, and simultaneously suppressing metal dust and preventing workpiece oxidation and discoloration.

[0015] 2. This integrated water-circulating copper wire wheel rust removal and polishing equipment utilizes the cooperation between the spiral clamping bolt and the motor mounting bracket in the drive transmission assembly. The bottom of the motor mounting bracket is hinged to the bottom of the frame, and the rear side is abutted by the spiral clamping bolt. Rotating the spiral clamping bolt will push the motor mounting bracket to flip outward around the hinge point, increasing the center distance between the driving pulley and the driven pulley, thereby automatically tensioning the transmission belt. Reverse rotation will loosen the belt. This achieves the effects of quick tensioning of the transmission belt without disassembly, preventing slippage during long-term use, stabilizing the spindle speed, and reducing downtime for maintenance.

[0016] 3. This integrated water-circulating copper wire wheel rust removal and polishing equipment utilizes the independent control settings of the motor switch, water pump switch, and speed controller in the electrical control components. This allows the power supply to the polishing motor and the circulating water pump to be independent. The motor switch independently controls the start and stop of the polishing motor, and the water pump switch independently controls the start and stop of the circulating water pump. The water supply can be turned on separately to test the water circuit or to adjust the machine under no-load conditions without starting the polishing spindle. At the same time, the speed controller is electrically connected to the motor to achieve stepless speed regulation of the copper wire wheel. This achieves the effects of flexible and convenient process adjustment, adaptability to the polishing process requirements of various metal workpieces, and improved surface processing consistency of workpieces.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 As shown, the system includes a frame, a polishing spindle assembly, a drive transmission assembly, a water circulation spray assembly, and an electrical control assembly. The polishing spindle assembly is horizontally mounted in the middle of the frame. The drive transmission assembly is mounted in the lower part of the frame and is connected to the polishing spindle assembly via a transmission belt 10. The water circulation spray assembly is fixed in the lower middle part of the frame and sprays water towards the polishing area of ​​the polishing spindle assembly. The electrical control assembly is mounted in the upper front part of the frame and is electrically connected to both the drive transmission assembly and the water circulation spray assembly. During operation, the drive transmission assembly transmits power to the polishing spindle assembly via the transmission belt 10, causing the copper wire wheel to rotate at high speed for polishing. Simultaneously, the water circulation spray assembly sprays cooling water into the polishing area. The electrical control assembly controls the start / stop and speed of the drive transmission assembly and the water circulation spray assembly. All components are integrated within the frame to form an integrated operating system, achieving coordinated operation of water supply, polishing, and drainage, thus improving the overall operating efficiency and stability of the equipment.

[0021] First, the polishing spindle assembly includes a rotating shaft and retainer 5 and a copper wire wheel rotating shaft 6. The rotating shaft and retainer 5 is horizontally locked onto the crossbeam of the frame. The copper wire wheel rotating shaft 6 extends horizontally from the operating side of the frame. A copper wire wheel is mounted on the outer end of the copper wire wheel rotating shaft 6, and a driven pulley is mounted on the inner end. During operation, the rotating shaft and retainer 5 firmly supports the copper wire wheel rotating shaft 6 on the frame. Driven by the driven pulley, the copper wire wheel rotating shaft 6 rotates, which in turn drives the copper wire wheel at the outer end to rotate at high speed. The copper wire wheel contacts and rubs against the workpiece surface to achieve rust removal, deburring, and polishing. The horizontal locking structure of the rotating shaft and retainer 5 ensures the coaxiality and stability of the copper wire wheel rotating shaft 6 during operation, avoiding vibration during polishing and improving the surface finish of the workpiece.

[0022] Secondly, the water circulation spray assembly includes a circulating water nozzle 7, a circulating water tank 8, and a circulating water pump 9. The circulating water tank 8 is horizontally fixed to the lower crossbeam of the frame. The circulating water pump 9 is placed inside the circulating water tank 8. The outlet of the circulating water pump 9 is connected to a pipeline that extends upward to the top of the frame. The end of the pipeline is bent to form the circulating water nozzle 7, which sprays water directionally towards the contact area between the copper wire wheel and the workpiece. During operation, the circulating water pump 9 draws water from the circulating water tank 8, pressurizes it through the pipeline, and delivers it to the circulating water nozzle 7 at the top. The circulating water nozzle 7 sprays cooling water directionally onto the contact friction area between the copper wire wheel and the workpiece, carrying away the frictional heat generated by polishing and preventing the workpiece from discoloring due to high-temperature oxidation. At the same time, it suppresses the flying of metal dust. The wastewater after spraying flows back to the circulating water tank 8 below by gravity, forming a continuous water circulation spray, ensuring the cooling and dust reduction effect of the polishing area.

[0023] Furthermore, the electrical control components include a power indicator 1, a motor switch 2, a water pump switch 3, and a speed controller 4. The speed controller 4 is electrically connected to the motor 11. The motor switch 2 is connected in series in the power supply circuit of the motor 11, and the water pump switch 3 is connected in series in the power supply circuit of the circulating water pump 9. The power supplies for the motor 11 and the circulating water pump 9 are independent of each other. The power indicator 1 is connected in parallel to the power input terminal of the whole machine. In use, after the whole machine is powered on, the power indicator 1 lights up to indicate that the device is in standby mode. After closing the motor switch 2, the motor 11 is powered on and drives the copper wire wheel to rotate. After closing the water pump switch 3, the circulating water pump 9 starts to spray water. Since the power supplies for the motor 11 and the circulating water pump 9 are independent of each other, the water pump switch 3 can be turned on separately for water circuit debugging without starting the copper wire wheel. The motor switch 2 can also be turned on separately for no-load speed regulation. The speed controller 4 can adjust the speed of the motor 11 according to the material of the workpiece, thereby adapting to the polishing process requirements of different workpieces.

[0024] Furthermore, the drive transmission assembly also includes a motor 11, a motor mounting bracket 12, and a spiral clamping bolt 13. The motor 11 is mounted on the motor mounting bracket 12, and the output shaft of the motor 11 is equipped with a drive pulley. The drive pulley is connected to the driven pulley at the inner end of the copper wire wheel shaft 6 via a transmission belt 10. The bottom of the motor mounting bracket 12 is hinged to the bottom of the frame. During operation, the drive pulley on the output shaft of the motor 11 drives the driven pulley at the inner end of the copper wire wheel shaft 6 to rotate via the transmission belt 10, thereby transmitting the power of the motor 11 to the copper wire wheel shaft 6. The motor mounting bracket 12 provides stable mounting support for the motor 11, and its structure of being hinged to the bottom of the frame allows the motor mounting bracket 12 to swing around the hinge point, providing a structural basis for subsequent belt tension adjustment and ensuring the smoothness and reliability of the transmission process.

[0025] Furthermore, a screw clamp 13 is installed on the rear side of the motor mounting bracket 12. The screw end of the screw clamp 13 abuts against the rear side of the motor mounting bracket 12. Rotating the screw clamp 13 pushes the motor mounting bracket 12 to flip outward around the hinge point to tension the transmission belt 10. Rotating the screw clamp 13 in the opposite direction loosens the transmission belt 10. When the transmission belt 10 becomes loose after long-term use, rotating the screw clamp 13 causes its screw to extend forward. The screw end pushes against the rear side of the motor mounting bracket 12, causing the motor mounting bracket 12 to flip outward around the bottom hinge point. The motor 11 moves outward along with the motor mounting bracket 12, increasing the center distance between the driving pulley and the driven pulley, thereby tensioning the transmission belt 10. Tension adjustment can be completed without disassembling the belt or motor. Rotating the screw clamp 13 in the opposite direction loosens the transmission belt 10 for replacement. The operation is convenient and reduces downtime maintenance time.

[0026] Furthermore, a filter screen is installed inside the circulating water tank 8. The filter screen is horizontally mounted at the top of the circulating water tank 8. Wastewater carrying metal fragments flows back to the circulating water tank 8 by gravity and is filtered by the filter screen. The filtered water is then pumped back to the circulating water nozzle 7 by the circulating water pump 9 for reuse. During operation, wastewater carrying copper and metal fragments flows back to the circulating water tank 8 by gravity from the polishing area. The wastewater first passes through the filter screen at the top, which intercepts the solid fragments above the screen. The filtered clean water falls into the lower part of the circulating water tank 8 and is then pumped by the circulating water pump 9 to the circulating water nozzle 7 for reuse. The filter screen effectively prevents metal fragments from entering the circulating water pump 9 and pipelines, causing wear or blockage, extending the service life of the pump and pipelines, and ensuring the cleanliness of the circulating water.

[0027] Furthermore, the electrical control components are arranged sequentially from top to bottom on the front of the frame: speed controller 4, power indicator 1, motor switch 2, and water pump switch 3. This arrangement allows operators standing to directly observe the power indicator 1's energization status and easily operate the motor switch 2 and water pump switch 3. The speed controller 4, located at the top, facilitates observation of the speed display and parameter adjustment. This rational arrangement prevents accidental activation during operation, improving the equipment's ease of use and safety.

[0028] Finally, the frame is a stainless steel welded enclosed vertical frame. The polishing spindle assembly, drive transmission assembly, water circulation spray assembly, and electrical control assembly are all integrated and installed within the vertical frame. The power supply lines are built into the frame and insulated and waterproofed. The stainless steel welded enclosed vertical frame features high structural strength and corrosion resistance, making it suitable for the humid conditions of wet polishing. The integration of all functional components within the frame results in a compact structure and small footprint. The power supply lines are built into the frame and insulated and waterproofed, preventing exposed wiring from being corroded by sewage and copper wire debris, ensuring the electrical safety of the equipment. The integrated design of the entire machine improves its stability and durability, and reduces the failure rate.

[0029] Working principle: Power indicator 1 lights up, indicating that the equipment has entered the power-on standby state. The operator first closes the water pump switch 3 separately. After the circulating water pump 9 is powered on and starts, it draws stored water from the circulating water tank 8 and pressurizes it through the connecting pipeline to the top of the frame. The circulating water nozzle 7 formed by the bend at the end of the pipeline sprays water in a directional direction onto the area where the copper wire wheel contacts and rubs against the workpiece. At this time, it is possible to observe whether the spray coverage is accurate and whether the path of the sewage flowing back into the circulating water tank 8 below by gravity is unobstructed. After the water circuit is debugged, the formal operation stage can begin. Then, the motor switch 2 is closed, and the motor 11 is powered on and starts running. The drive pulley installed on the output shaft of the motor 11 rotates synchronously. The drive pulley is driven by the transmission belt. Power is transmitted from belt 10 to the driven pulley at the inner end of the copper wire wheel shaft 6. The copper wire wheel shaft 6 rotates smoothly around its own axis under the lateral locking support of the shaft and the retainer 5, thereby driving the copper wire wheel mounted at the outer end of the shaft to rotate at high speed. The operator, according to the material of the workpiece and the polishing requirements, continuously adjusts the output speed of motor 11 via speed regulator 4 to ensure that the copper wire wheel shaft 6 and the copper wire wheel reach the rotational speed set by the process. During the formal polishing operation, the operator holds the workpiece and places the surface to be treated against the high-speed rotating copper wire wheel. The copper wires on the surface of the copper wire wheel continuously rub against the workpiece surface, achieving rust removal, deburring, and polishing. Simultaneously, the circulating water nozzle 7 continuously sprays water onto the friction contact area. Cooling water is sprayed, directly carrying away the high temperature generated by the friction between the copper wire and the workpiece, preventing the workpiece surface from oxidizing and discoloring due to overheating. Simultaneously, wet operation completely suppresses metal dust. Wastewater carrying copper shavings and metal fragments flows downwards into the circulating water tank 8 under gravity. The wastewater first passes through a filter screen installed at the top of the circulating water tank 8, where solid debris is intercepted. The filtered clean water falls into the lower part of the circulating water tank 8, and is then pumped by the circulating water pump 9 and re-transported to the circulating water nozzles 7, forming a continuous circulating and reused cooling water system. When the drive belt 10 becomes stretched and loose after long-term use, the screw clamp 13 installed on the rear side of the rotating motor mounting bracket 12 is turned after shutdown. The screw of the screw clamp 13... Extend forward and push the rear side of the motor mounting bracket 12, causing the motor mounting bracket 12 to flip outward around the bottom hinge point. The motor 11 mounted on the motor mounting bracket 12 moves outward accordingly, increasing the center distance between the driving pulley and the driven pulley, thereby automatically tensioning the transmission belt 10. Adjustment can be completed without disassembling the belt or motor. Rotating the spiral clamping bolt 13 in the opposite direction can loosen the transmission belt 10 for replacement. After the operation is completed, first turn off the motor switch 2 to stop the motor 11 from running. After the copper wire wheel shaft 6 and the copper wire wheel have completely stopped rotating, turn off the water pump switch 3 to stop the circulating water pump 9 from supplying water. Finally, periodically remove the filter screen in the circulating water tank 8 to clean the accumulated copper shavings and metal impurities to ensure that the subsequent circulating water path is unobstructed.
